An image processing method includes inputting electronic image data to be scrambled, decomposing the input electronic image data into n colors (n is an integer) and producing m pieces of color decomposition data for each color (m is an integer), producing palette data in which each of the m pieces of color decomposition data is assigned a palette identification number, producing palette exchange data based on predetermined conditions, exchanging palette identification numbers of the color decomposition data based on the produced palette exchange data, and synthesizing the m pieces of color decomposition data whose palette identification numbers are exchanged, encoding the synthesized data, and outputting the encoded data as a piece of scrambled image data.
